To all whom it may concern:

Be it known that I, ANNE Vonrnnnc, a subject of the Queen of Holland, and resident of Racine, in the county of Itacine and State of Wisconsin, have invented certainnew and useful Improvements in Perpetual Calendars; and I lowing is a full, clear, and exact description thereof. Y

My invention pertains to new and useful calendars, particularly of that type which are changed day by day to display the proper date.

The primary object of the invention is to provide a simply constructed'device of this nature in which the date characters are e'f' parts which will be hereinafter more particu-" larly described and'claimed and shown in the accompanying drawing wherein:

Figure 1 represents a front elevational view of a calendar constructed in accordance with the invention.

Fig. 2 is a horizontal sectional view on the plane of the line 2-2.of Fig. 1.

Fig. 3 1s a fragmentary rear elevational view showing particularly the means for rotatably supporting one of the date character disks.

Fig. 4 is a detail transverse sectional view through a calendar showing a modified means for rotatably mounting one of said date character disks, and

' Fig. 5 is a plan view of one of said disks.

In the present showing of the invention I have illustrated my improved date display means associated with a frame carrying a mirror. This may be plain or contain suitable legends of an advertising nature, or the mirror may be omitted and the portion of the device occupied thereby provided with advertising matter or the like. Various; other changes may be made in the calendar device and in the manner of assembling the do hereby declare that the folvarious parts thereof withoutdeparting from or sacrificing any of the principles of the invention.

Referring now more particularly to the several figures of I the .drawing, it will be noticed that the -numeral 1 denotes a front or face plate of a; suitablesize and shape having its upper portion provided with an opening 2 through which said mirror 3 is visible, while the reference character 4; designates a backing plate of the same size and shape as the plate 1, both of which plates 'aremounted within a suitable frame 5. The two plates 1 and a. are spaced apart the thickness of-the mirror 8 by means ofspacing strips 6 or. the I like. l

Below the mirror 3 I preferably'locate my improved date display means- In the pres ent instance I display the date of'the week, the day of the month, the. month of the year;

and the number of the year in horizontal 1 alinement across the face plate 1 between'the lower edge of the opening 2 and the bottom of the frame 5. The characters or symbols.

representing such dates are, visible through a series of openings 7 cut in the face plate 1 and arranged in a horizontal row.

The necessary symbols are printed or otherwise fashioned on a series of disks 8, one of which disksis adapted to be located behind each of the openings? and between the face plate 1 and backing plate 4:. In

'asmuch as certain of the disks necessarily contain more symbolsthan the others said disks are of dissimilar sizes and are there fore not arranged in alinement as are the openings 7 The backing plate 4: isprovided with a series of circular openings 9, one of "which is alined with the center of each disk 8. Through these openings'9 the disks may be revolved to'bring the proper date symbol in registration with the openings' 7, and the means for turning the disk can be carried out in any desired manner-such as by the arrangement illustratedl I The disk rotating means shown in Figs.

2, 3 2111(15 consists in stamping or otherwise forming a substantially rectangular tongue 10 in approximately the center of'each of the disks 8.

resultant tongue; is bent on a line passing diametrically therethrough, which tongue is substantially ofa widthequal to the diam eter ofthe several openings 9. Thus by ex- In other words each of said disks is provided witha U-shaped cut and the tending the tongues 10 through the openings 9, handles are formed for manipulatlng the disks.

In the form of the invention shown in Fig. 4, the portion 11 of the backing plate which has been cut out in forming the opening 9 is replaced and secured to the disk 8 and to a circular rotating plate 12 by a rivet 13. It will be noticed from this figure that the plate 12 is considerably larger than the opening 9 so that when the rivet is in place removalof the disk 8 is prevented.

F rom, the foregoing description taken in connection with the accompanying drawing, it will be seen that I have invented a very simply constructed calendar device which, because of the simplicity thereof and in view of the cheapness of the materials from which it may be formed, may be inexpensively manufactured. As a result such a 'device'as this may find a novel advertising display means. other hand if carefully made it will form a very attractive calendar which may be sold at a considerable price.

I claim: 1. In a device of the class described, a

7 face plate having a series of sight openings of said series formed therein, the opening circular disks being alined, a plurality of ready market as a On the r ing characters thereon to be registered with one of said openings, a backing plate having a series of openings, said last mentioned openings being disalined, each being in reg,- istration with the center of one of said disks, a tongue struck from each of said disks extending through the adjacent opening in the backing plate for rotating the same, and a spacing strip between the two plates and having openings therein in'which said disks are fitted.

v2. In a device face plate having a series of sight openings formed therein, the openings of said series being alined, a plurality of disks disposed behind the'face plate, each having characters thereon to be registered with one of said openings, a backing plate having a series of openings, said last mentioned openings being disalined, each being in registration with the center of one of said disks,-

of the class described, a
